Crypto Price Move Alert
This automation checks a cryptocurrency's price every 15 minutes using CoinGecko's free, keyless public API, logs every reading, and sends an instant Telegram alert the moment its 24-hour change crosses a threshold you set. Monitoring only — it never places trades, generates signals, or gives investment advice.
Automation flow
Every 15 Minutes
A schedule trigger checks the price continuously.
Fetch Price Data
CoinGecko's free public API is queried — no key needed.
Check Move Threshold
The 24h change is compared against your threshold.
Log Price
Every check builds a full price history in Sheets.
Send Alert
A Telegram alert fires the instant a big move happens.
How it works
- 1Every 15 minutes, the current price and 24-hour change for your chosen coin are fetched from CoinGecko's free API.
- 2Every reading is logged to your sheet, building a full price history over time.
- 3If the absolute 24-hour change is at or above your threshold, a Telegram alert fires immediately with the current price and change percentage.

Make it yours
- Track multiple coins by duplicating the fetch/check/log chain per coin, or loop over a list of coin IDs stored in a sheet.
- Swap Telegram for Slack or email — the alert step is a single node, easy to replace.
- Add a second, tighter threshold (e.g. 2%) that logs quietly without alerting, to build a denser price history for your own charting.
